Resumo: | The macroscopic morphology of genital tract of six adult female paca (Cuniculus paca) was studied through dissection of abdominal and pelvic cavities immediately after death. The ovaries have ovoid shape, dorsal-ventrally flattened, whitish yellow color with small red spots on its surface, located in sublombar situation, caudally to the kidneys, surrounded by a shallow bursa and fixed by the mesovarium; the oviduct is a pair of sinuous tubes, continuous with the ovaries, inserted in the mesosalpinx and extending up to the beginning of each correspondent uterine horn. The uterus horns are rectilinear and attached in the abdominal walls by the mesometrium, each horns extends caudally into the pelvic cavity and are linked by intercornual ligament, the ventral surface chiefly contacts the bladder; two cervices are present, although the uterine septum is incomplete, characterizing the presence of two internal uterine ostia and one external uterine ostium, considering this uterus as an incomplete duplex. The vagina is a tubular organ that is positioned ventrally to the rectum and dorsally to the urinary bladder and urethra; urethral duct is placed apart of the vaginal canal, characterizing the absence of the vestibulum; the vulva presents itself planed, with reduced vulvae lips, the clitoris is a conical structure with two prominent pointed structures at its distal region. There were no differences statistically significant in measurements made in the ovaries, oviducts and uterine horns, when comparing the right and left sides. |

Os ovários apresentam forma ovoide, achatados dorso-ventralmente, de coloração amarela esbranquiçada com pequenos pontos avermelhados em sua superfície; têm localização sublombar, caudal aos rins; estão envoltos por uma rasa bolsa ovárica e fixados pelo mesovário; a tuba uterina é um órgão par, de aspecto sinuoso, contínua aos ovários, estando inserida na mesossalpinge e se estendendo até o início de cada corno uterino correspondente. Os cornos uterinos retilíneos fixam-se à parede abdominal pelo mesométrio e se unem pelo ligamento intercornual na altura da entrada da pelve, onde se posicionam dorsalmente à vesícula urinária; duas cevices estão presentes, embora o septo uterino que as separa seja incompleto, caracterizando presença de dois óstios uterinos internos e um único óstio uterino externo, considerando-se este útero como duplo incompleto. A vagina é um órgão tubular que se posiciona ventral ao reto e dorsal à vesícula urinária e à uretra, não se verificou a presença de vestíbulo e a vagina e a uretra não possuem ponto comum de convergência, abrindo-se, cada uma delas, diretamente na região vulvar, que se apresenta plana, com reduzidos lábios vulvares, apenas o clitóris de forma cônica é pouco proeminente e apresenta duas estruturas pontiagudas em sua região distal. Não se verificaram diferenças estatisticamente significativas nas mensurações realizadas nos ovários, tubas uterinas e cornos uterinos, ao se comparar os antímeros direito e esquerdo.Universidade de São Paulo.

The ovaries have ovoid shape, dorsal-ventrally flattened, whitish yellow color with small red spots on its surface, located in sublombar situation, caudally to the kidneys, surrounded by a shallow bursa and fixed by the mesovarium; the oviduct is a pair of sinuous tubes, continuous with the ovaries, inserted in the mesosalpinx and extending up to the beginning of each correspondent uterine horn. The uterus horns are rectilinear and attached in the abdominal walls by the mesometrium, each horns extends caudally into the pelvic cavity and are linked by intercornual ligament, the ventral surface chiefly contacts the bladder; two cervices are present, although the uterine septum is incomplete, characterizing the presence of two internal uterine ostia and one external uterine ostium, considering this uterus as an incomplete duplex. The vagina is a tubular organ that is positioned ventrally to the rectum and dorsally to the urinary bladder and urethra; urethral duct is placed apart of the vaginal canal, characterizing the absence of the vestibulum; the vulva presents itself planed, with reduced vulvae lips, the clitoris is a conical structure with two prominent pointed structures at its distal region. There were no differences statistically significant in measurements made in the ovaries, oviducts and uterine horns, when comparing the right and left sides. |
